# Please see vsftpd.conf. for all compiled in defaults.

#

# Uncomment this to allow local users to log in.
# 之前说到我们用ROOT/ROOT来访问ftp，我们这里，ROOT/ROOT是我们的linux可以登录的用户名密码。要允许这类用户访问ftp，需要开启下面的选项

local_enable=YES

#

# Uncomment this to enable any form of FTP write command.
# 要允许写入操作。否则应该不能上传文件

write_enable=YES

#

# Default umask for local users is . You may wish to change this to ,

# if your users expect that ( is used by most other ftpd's)

local_umask=

#

# Uncomment this to allow the anonymous FTP user to upload files. This only

# has an effect if the above global write enable is activated. Also, you will

# obviously need to create a directory writable by the FTP user.
# 匿名上传，需要配合write_enable=yes

anon_upload_enable=YES

#

# Uncomment this if you want the anonymous FTP user to be able to create

# new directories.
# 允许匿名用户创建目录;

anon_mkdir_write_enable=YES
#控制匿名用户对文件和文件夹的删除和重命名

anon_other_write_enable=YES

#

# Activate directory messages - messages given to remote users when they

# go into a certain directory.

dirmessage_enable=YES

#

# The target log file can be vsftpd_log_file or xferlog_file.

# This depends on setting xferlog_std_format parameter

xferlog_enable=YES

#

# Make sure PORT transfer connections originate from port  (ftp-data).

#

# If you want, you can arrange for uploaded anonymous files to be owned by

# Enable this and the server will recognise asynchronous ABOR requests. Not

# recommended for security (the code is non-trivial). Not enabling it,

#async_abor_enable=YES

#

# By default the server will pretend to allow ASCII mode but in fact ignore

# the request. Turn on the below options to have the server actually do ASCII

# mangling on files when in ASCII mode.

# Beware that on some FTP servers, ASCII support allows a denial of service

# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd

# predicted this attack and has always been safe, reporting the size of the

# raw file.

# ASCII mangling is a horrible feature of the protocol.

# (default follows)

#banned_email_file=/etc/vsftpd/banned_emails

# You may specify an explicit list of local users to chroot() to their home

#

# You may activate the "-R" option to the builtin ls. This is disabled by

# default to avoid remote users being able to cause excessive I/O on large

# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

# the presence of the "-R" option, so there is a strong case for enabling it.
